STEAM-PUM P.

SPECIFICATION forming part of Letters Patent No. 732,713, dated July '7, 1903. Application filed September 15, 1902. Serial No. 123,451. (No model.)

T0 at whom it may concern.-

zen of the United States, residing at Owatonna, in the county of Steele and State of Minnesota,have invented certainnew and useful Improvements in Steam-Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which construction will later appear.

it appertains to make and use the same.

My invention has for its object to provide an improvement in steam-pumps; and to this end it consists of the novel devices and combinations of devices hereinafter described, and defined in theclaims.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views. 7

Figure 1 is a perspective view showing a steam-pum p embodying the several features of my invention. Fig. 2 is a detail, principally in side elevation, but with some parts sectioned and others broken away, showing the combined crank-disk and valve-actuating cam. Fig. 3 is a horizontal section on the line 00 m of Fig. 1, some. parts being broken away; and Fig. 4: is a detail in elevation looking at one side of the supporting yoke or frame of the pump in a direction from the inside toward the outside thereof.

The numeral 1 indicates the cylinder, and the numeral 2 the steam-chest, of a steam-engine.'

Thenumeral 3 indicates the cylinder of a pump.

half-bearing 6, to which is bolted or otherwise detachably secured ahalf bearing or box 7. The axis of the journal afforded by the box-sections 6 and 7 intersects the common axes of the cylinders 1 and 3 at a right angle.

The numeral 8 indicates along heavy pis- -5o ton-rod, which is provided at its ends with ordinary pistons which work in the cylinders l and 3 in the ordinary way. The piston-rod 8 is provided with a wrist-pin 9, the end of which is preferably reduced, as shown in Fig. 3, and'works in a vertical channel or groove 10, formed on one side of the yoke 4, as shown, .by a pair of projecting parallel flanges. The guide-channel lOterminates at its lower end at apoint'wherethe frame or yoke bulges abruptly outward at 4. The purpose of this vided with the disk 13. The disk 13 is pro-' vided with'a crank-pin 14, which projects from its inner face, and in its outer face it is provided with a profile cam-groove 15. A pitman 16 connects the crank-pin 14 of the said disk 13 to the wrist-pin 9 of the piston-rod 8.

The distribution-valve of the steam-engine, which is of the ordinary or any suitable construction and works in the steam-chest 2, is not shown; but its stem 17 works downward through a stuffing-box 18 in the lower end of the steam-chest, and its lower end works through a guide-block 19, bolted or otherwise secured to the bulged side 4* of the yokeframe at just above the box-sections 6 and 7. The piston-rod 17 is thus mounted for true vertical movements, and at its extreme lower e'nd'it is provided with a roller 20, which Works in the cam-groove 15 of the disk 13.

The'crank-disk 13 is thus made to serve the double function of cam and crank. The camgroove 15 mustof course have the proper form to impart the desired movements to the admission-valve, this being Well understood. The valve-stem 17 receives a straight-line reciprocating movement directly ffom-the said cam. This construction is not only simple and of small cost, but is extremely efficient.

downward far enough to carry the wrist-pin 9 below the bulged section 4 of the yoke 4.

'the piston.

The yoke t forms a very good support for the working parts of the pump and rigidly ties together the two cylinders 1 and 3. Furthermore, it is disposed in the best way to receive the end thrusts on the pitman l6.

Bymeans of the hand-wheel12 the pump can be easily started into action by the movement of the pitman 16 from the dead-center. Furthermore, by means of the said handcrank the pump may be run by hand. The said wheel 12 also serves as a fiy-wheel for the crank-disk 13.

It will of course be understood that the pump described is capable of modification within the scope of my invention, as herein set forth andclaimed.

What I claim, and desire to secure by Letters Patentof the United States, is as follows:

1. In a pump, the combination with a frame and aipiston-rod, of a crank-disk having on one face a wrist-pin, and on its other face a valve-actuating cam, a pitman connected to the wrist-pin of said crank-disk and to said piston-rod, and a valve-stem having a projection subjectto the cam of said crank-disk, substantially as described.

2. In a pump, the combination with a pair of cylinders, of a frame connecting the same, and a piston-rod cooperating withthe said cylinders, of a crank-disk mounted on said frame, a wrist-pin on said piston-rod, the projecting end thereof working in a longitudinal groove, formed in one side of said frame, and a pitman connecting said crank-diskto the wristpin of said piston-rod, and held in working position by the grooved side'of said frame, substantially as described.

3. In a pump, the combination with the cylinders 1 and 3, of the frame or yoke 4 rigidly connecting said cylinders, provided at one side with the groove 10, lateral bulge 4: and half-boxes 6 and 7, with the piston-rod 8 cooperating with both cylinders and provided with a wrist-pin 9 the outer end of which works in said groove 10, the crank-disk 13 having a shaft mounted in the beari-ngfi 7, providedat its inner face with a crank-pin 14 and on .its outer face with a cam-groove 15, the pitman 8 connecting .said crank-pin 14 and wrist-pin 9 and held in place by the side of said frame 4, and the valve-stem 17 Working through a fixed bearing 19 on the FRED D.
